[amsat-bb] question on g5400 controller

[Robert MacHale]

http://n3ujj.com/manuals/YAESU%20g5400b.pdf 

Page 3 says 24 VDC. 

I am guessing that is for full speed and then 12 VDC is half speed.
The only concern I would have is that it may be expecting a motor controller to send it positive volts for turning one way and negative volts for turning the other way; right?
Let me know if you figure it out.

 I am trying to help out someone with a controller. The control box works manually but does not work with his Sat32 controller. I am not familiar with the software but am trying to diagnose the control box. I am assuming a few volts on the DIN connector that correlate with the relay switching transistor should cycle the relays. If my thinking is correct how many volts would I apply to the DIN pins to prove out the controller is working correctly? Hope this makes some sense. Thanks Mike WB8PFZ
